The focus was more on how the Sony drive became the standard and less about all the competing formats. The CFD was the only serious competition and, in the US at least, it never reached the levels of putting up a fight like the ZipDisk vs. SuperDisk or Blu-Ray vs. HD-DVD.

The Amstrad was the only system OEM I found that really used it, so while it did have some market it definitely wasn't wide spread to other systems like the BBC Micro, Acorn, or (Proper) Sinlcairs.
